I have just aquired a Ajutor e-scooter which has a 36v 200w brushless motor, it would appear somebody has butchered the controller wiring, the scooter has no motive power though everything else works, lights etc, I have 36v at the power leads on the controller.I need to source a wiring diagram or any idea,s on how to test?

It is very possible that your battery voltage is too low to operate the motor! How many batteries, and what kind, are they? If you have 3 lead-acid type 12 volt batteries, fully charged voltage should be over 40 volts, not 36. There are also versions of this vehicle that are 48 volts, with 4 batteries, measuring about 55 volts when fully charged. (Most 12 volt batteries are over 13 volts each, if just recently fully charged)-Bob

I have 3x 12 lead acid batteries, the multimeter is showing about 38 volts and the scooter gauge is showing nearly full charge, does anyone know of a replacement controller suitable for this bike, any help greatly appreciated.
